Can we estimate the shape and dimensions of the visible universe? Does it have a three dimensional form? If so, where is the centre?Shape of the visible universe: spherical, 3 dimensional.
Radius: About 13 billion lightyears.
We don't know how big the unseen portion of the Universe is, and don't have a good idea to its form and shape. But, the visible portion is roughly a sphere with Earth at the center.
